United States Fish and Wildlife Serv. v. Sierra Club, Inc.
The Supreme Court ruled 7–2 that draft biological opinions prepared by federal wildlife agencies are shielded from public disclosure requests, because agency leaders never approved them or treated them as final decisions — even though the drafts were the agencies' last assessment of a proposed EPA rule.
The decision reinforces the government's ability to protect preliminary internal thinking from mandatory disclosure under the Freedom of Information Act, drawing a clear line between documents that carry real legal weight and those that are still part of an ongoing deliberation.
“What matters, then, is not whether a document is last in line, but whether it communicates a policy on which the agency has settled.”
The majority's core test for when an internal document counts as 'final' and loses its FOIA protection.
How it got here: The district court ruled for the Sierra Club; the Ninth Circuit affirmed, holding the draft opinions were functionally final; the federal agencies asked the Supreme Court to step in and the Court agreed to hear the case.
The Case in Depth
What happened
The EPA was developing a rule about industrial cooling water intake structures — equipment that kills fish and other aquatic life. The Endangered Species Act required the EPA to consult with the U.S. Fish and Wildlife Service and the National Marine Fisheries Service. Agency staff completed draft biological opinions in December 2013 concluding the EPA's proposed rule would likely harm protected species. But agency leaders never approved those drafts, never sent them to the EPA, and eventually shelved them when the EPA revised its rule in 2014. The Sierra Club, an environmental organization, filed FOIA requests seeking the 2013 drafts, and the agencies refused to hand them over.
The question before the Court
Can federal wildlife agencies keep internal draft documents secret under FOIA when those drafts turned out to be their last word on a proposed rule — but were never officially approved or sent to the requesting agency?
The Court's answer
No — the draft biological opinions are protected from disclosure. The deliberative process privilege, incorporated into FOIA's Exemption 5, shields documents that are both "predecisional" (made before a final agency decision) and "deliberative" (part of the process of forming policy). Because the Services' decision-makers never approved the drafts or sent them to the EPA, the Court treated them not even as draft biological opinions but as "drafts of draft biological opinions" — clearly preliminary, clearly not final.
The Sierra Club argued the drafts had "operative effect" because the EPA revised its rule once it learned a jeopardy finding was coming. The Court rejected that theory: the operative-effect test asks whether a document carries direct legal consequences, not merely practical ones. Final biological opinions trigger real legal obligations; unapproved internal drafts do not. Because the Services never treated the documents as their settled view, the privilege applies.

Why it matters
Environmental groups, journalists, and others who use FOIA to scrutinize government decision-making will find it harder to obtain internal agency drafts, even when those drafts reflect the clearest available record of what an agency concluded. Agencies can keep draft documents off-limits as long as decision-makers never formally adopted them, regardless of whether the drafts effectively drove a regulated party's behavior.
What changes now
The case is sent back to the lower courts. On remand, the district court must determine whether any portions of the withheld documents can be separated out and disclosed — FOIA requires agencies to release any "reasonably segregable" parts of an otherwise exempt document. The Court's ruling does not permanently seal the documents; it means the lower court must do a more careful document-by-document review.
What this does not decide
The Court leaves open whether a draft biological opinion that agency leaders have clearly treated as final — for example, by signaling they will not change their conclusions — could still be shielded by the privilege. The ruling is limited to drafts that agency decision-makers never approved or forwarded, and says nothing about partial disclosure of segregable portions.
Concurrences and dissents
Dissent — Justice Breyer
Justice Breyer, joined by Justice Sotomayor, argued that a completed draft biological opinion — one whose environmental analysis and conclusions are finished, even if not yet formally issued — functions the same as a final biological opinion and should not be shielded by Exemption 5. He identified five reasons: draft opinions reflect final jeopardy conclusions, serve the same practical functions as final opinions, trigger EPA decision-making in practice, are routinely disclosed to the public anyway, and carry legal consequences under agency regulations. Breyer would have remanded to the Ninth Circuit to determine whether the specific documents were truly incomplete 'drafts of drafts' or were in fact finished draft biological opinions.
How the Court got there
The legal reasoning, step by step
- FOIA's Exemption 5 protects 'predecisional' and 'deliberative' documents — that is, documents generated before an agency's final decision and prepared to help the agency work out its position. Documents reflecting a settled, final agency decision do not qualify and must be disclosed.
- The Court's key interpretive move: a document is not 'final' simply because nothing came after it. Sometimes proposals 'die on the vine.' What matters is whether the agency actually treated the document as its final, settled view — not whether it happened to be the last one written.
- Applying that standard, the Court found the 2013 draft opinions were never treated as final. They were written by lower-level staff and sent up the chain for approval. Agency decision-makers never signed off, never sent the drafts to the EPA, and instead concluded 'more work needed to be done.' This makes them, in the Court's phrase, 'drafts of draft biological opinions' — even more preliminary than ordinary preliminary documents.
- The Sierra Club argued the drafts had 'real operative effect' because the EPA revised its rule after learning a jeopardy finding was coming. The Court rejected this effects-based test, explaining that 'operative effect' in its precedents refers to direct legal consequences — the kind a final biological opinion carries by altering the legal regime the EPA must follow — not the practical ripple effects any internal communication might cause.
- Because the Services did not treat the drafts as final, and because a purely practical-consequences test would swallow the deliberative process privilege by making nearly any influential memo 'final,' the privilege applies and the drafts are protected from FOIA disclosure.
